PCB-RE: Real World Examples by Keng Tiong Ng now available on Amazon for purchase HERE



About the Book:


Putting into practice what you've learned is perhaps the most challenging thing to do, especially if there is no practical and detailed example to take reference from. It's with this in mind PCB-RE: Real-World Examples is written.This book completes the earlier works of the author, namely The Art of PCB Reverse Engineering and PCB-RE: Tools & Techniques, by providing the reader an in-depth walk-through on how theory is put into practice. Together they form the trilogy on the PCB-RE subject.While the first book provides a simple example using an ISA-bus SCSI host adapter to illustrate the steps in doing manual PCB-RE, it serves only as a starting point for those embarking on this adventurous journey. Along the way, questions and difficulties will abound, and one is left wondering if the manual approach is even possible, if at all practical to begin with.This book expands on the practical aspect of PCB-RE by tapping on the invaluable experiences of engineers in this field, supplemented with the author's own example of a more complex board. Perhaps the contributions of like-minded engineers will afford budding enthusiasts a peek into the real-world workings of PCB-RE, so they can learn from the strategies and techniques described to develop their own methodologies. As far as the author's example goes, the illustrations are done using Microsoft Visio but the process of solving the interconnectivity puzzle is generic. Prior familiarity with the steps mentioned in his first two books, though not a necessity, is advantageous to get up to speed and essential if the reader intends to use the same diagramming tool.Hopefully, this book will give the reader new perspectives and ideas that will enrich his or her PCB-RE experiences and inspire more engineers to take up this challenging yet rewarding practice that is gaining recognition and importance in the PCB repair and refurbish industry.



Wind Turbine Repair


Ever wondered what it's like to repair electronics at 100M in the air?
Recently we were contracted to do repair and engineering work in the HUB of a wind turbine. The wind farm was in a remote location two hours north of Sault Ste. Marie. Once the equipment was hoisted up to the top of the tower it was now my responsibility to unload the equipment and diagnose the problem. This turbine (now out of warranty) had some issues with the control systems inside the HUB, knowing our wind experience and ability to repair electronics the customer asked if we would take a look at a problem they were having. After diagnosing the issue in the hub I was asked if I wanted a photo at the top of the tower and this is what we got!


ENA Electronics is pleased to announce that our head office has officially relocated to:

1527 Upper Ottawa Street Unit 8, Hamilton

This conveniently places us directly across from our Electronics Laboratory.

Now almost double the size of our previous office, this move embodies the growth ENA has experienced over the last 5 years.

This leap forward/jump comes alongside some exciting developments at ENA. In particular, the expansion of our Reverse Engineering department + new opportunities for us in the Wind Energy sector.

The larger facility will allow us to better serve all our customers as we continue to expand. While staying in Hamilton, we can continue to help build the growth of the tech space here.

All contact information will remain unchanged.

For any questions or concerns, we would be happy to hear from you at: [email protected]



Improving or modifying the existing firmware to add extra features is difficult without providing the source code (the original program in its original language), this is because, when a compiler compiles code for a programmed IC the compiled output is translated into machine code which is then downloaded into the IC. This machine code although not impossible to disassemble the machine code into assembly code + thus edit it, it is a process that is certainly not quick + can often result in limited results at best.


In situations where you need to edit or change the algorithm but you do not have the source code we recommend that you get in touch to see how we can help you rewrite your firmware.


We first start by reverse engineering your circuit board + finding out what inputs + outputs are connected to the programmed IC this allows us to make sure the functionality of the new firmware replicates the old. We then take these inputs + outputs + either replace the programmed IC with a modern equivalent or use the make + model of the original IC, buy a new one + then program it to have expanded functionality.


The benefits of redeveloping your firmware is that you will then be able to have backups of your new source file to use for future production + if your new programmed IC or microcontroller ever becomes obsolete you will have the source file allowing you to recompile the code for another microcontroller which is far quicker + faster than redevelopment.


Do you need firmware modifying or improving? If so get in touch to see what solutions we can offer you.

Servo Motor Repairs - Repair or Replace?



Here at ENA we can repair various servo motor brands. Typically, and almost always a repair is less expensive than a replacement. Our Technicians undergo strict testing procedures that vary based upon the brand, model, features and firmware.


First, we assess and inspect for aesthetic damage. Photos are taken, and appropriate software is used to communicate with the hardware checking that the encoder/resolver is working properly.


After this the nameplate data and maintenance info is compiled by our techs for later reference if necessary. Next, the servo motor is meter tested for insulation and resistance, this allows us to prevent further damage to the parts, insulation and winding. The Servo Motor is then connected to our state of the art Mitchell System in order to check its electromagnetic frequency, encoder or resolver feedback and commutation alignment. We want to ensure everything is functioning correctly! We then perform a 100% component test including looking at to ensure there are no connection issues, magnet failures, or winding failures. Print outs of the test data can be given on request.


Once our technicians finish the repair, they reassemble the servo motor for cleaning and painting. Finally protection is added to the motor, this means that when you receive your motor you can be assured it has the ENA Electronics seal of approval.


Why not have a look at some of our previous servo motor work? As the GTA (Greater Toronto Areas) premium motor repair shop we are proud to offer free pickup and delivery with one of our authorised account managers, we've got you covered from Hamilton to Burlington, Oakville, Toronto and beyond.
